win 55,2122 mesylate

(±)-WIN 55,212-2 is a potent aminoalkylindole cannabinoid (CB) receptor agonist with a Ki value of 62.3 and 3.3 nM for human recombinant central cannabinoid (CB1) and peripheral cannabinoid (CB2) receptors, respectively. In contrast, the enantiomer (-)-WIN 55,212-3 acts a partial inverse agonist at CB1 (pIC50 = 5.5) and as a competitive neutral antagonist of CB2, reversing the inverse agonism evoked by SR 144528 (pEC50 = 5.3). (+)-WIN 55,212 (mesylate) is a mixture of the two enantiomers, (+)-WIN 55,212-2 and (-)-WIN 55,212-3.

(-)-WIN 55,212-3 mesylate 是 WIN 55,212-2 mesylate的低活性对映异构体，无神经保护活性和减少肠道运输的作用。(-)-WIN 55,212-3 mesylate是一种大麻素受体激动剂， 可用于研究神经系统疾病。
